Anyone know what the proper offsets should be for the two switches (and their associated FAULT lights) indicated in the attached screenshot?

In the default pm777.txt file, they're listed as HydEng3Sel 0x56D4 and HydEng4Sel 0x56D5. Clearly, the 777 only has two engines, and further, these are not repeats of regular Primary Hydraulic Pumps, they are air-driven pumps for extra loads or in case a primary pump pressure is low.

According to Boeing, they are Demand Pump Selectors and the corresponding FAULT lights indicate 1) low demand pump output pressure 2) excessive demand pump fluid temperature, or 3) demand pump is selected OFF.

Can we get these offsets if they don't exist?
